SPECIFICATION forming part of Letters Patent No. 650,420, dated May 29,1900.

Application filed November 11, 1889. Serial No. 329 857. (N0 model.)

To 610% whom it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, a citizen of the UnitedStates, residing at Newton, in the county of Middlesex and State ofMassachusetts, and having my post-office address at West Newton, in thesame county and State, have invented a new and useful Improvement inHeel-NailingMachines,of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings,formin g apart of this specification, in explaining its nature.

The invention is an improvement upon that described in my Letters Patentof the United States dated February 14, 1899, No. 619,707; and itrelates especially to the devices for presenting the work to thenail-driving and top-lift-spanking appliances, whereby the constructionof the jacking mechanism is simplified and the machine adapted to be fedwith shoes from the. back of the machine as well as from the front.

Referring to the drawings, Figure 1 is a view, part in vertical sectionfrom side to side and part in front elevation, of a machine having thefeatures of my invention. Fig. 2 is a view in vertical section, takenfrom front to rear, of the machine. Fig. 3 is a view in horizontalsection upon a line between the nailing devices and the jacks and inplan of parts below said line. Fig. 4 is a view representing the sameportions of the machine represented in Fig. 3, but in a differentposition. Fig. 5 is a view in elevation, enlarged, of the upper part ofthe machine, including the cross-head and rotary head and headturningmechanism. Fig. 6 is a view in rear elevation of a portion of thehead-turning mechanism. Fig. 7 is a view in elevation of the rotary headdetached from the cross-head.

A-is the frame of the machine. Its sides a a and cross bed or piece aare integral or in one casting.

B is the cross-head. It carries the rotary head I), preferably havingthree groups of operating devices, each of which groups comprises theheel-nailing apparatus b and the top-lift spanker b As these appliancesare described in said patent, I need not further refer to them here. Iwould say, however, that so far as the principal features of the presentinvention are concerned it-is not necessary to employ more than onegroup of operating devices and in some instances only" theheel-attaching devices.

O is the shaft of the machine. cranks c c, which are connected with thecross-head B by the connecting-rods c 0 The shaft is supported bybearing-blocks c bolted to the bed or cross-piece a D is a fly-wheelwhich also serves as a pulley. It is secured to the main shaft 0, andthe shaft has the outer bearing din the standard d. d is a member of theclutch on the It has the fly-wheel, and d is a member of the clutch onthe shaft. It is operated as follows: d is a lever pivoted at and forkedat its upper end to support rolls to enter the groove d in the member 61of the clutch. d is a spring which serves when the lever 61 is releasedto move the member d of the clutch into engagement with the member 01 Itextends from the lower end of the lever to the frame of the machine. dis a latch-lever pivoted at d to the lever d having the latch (Z and 7connected at its end d by the rod 01 with the treaclle 61 A spring (1serves to hold this latch-lever up. The lever d is pivoted upon the endof the shaft cl. This shaft carries a gear d which makes one revolutionfor every two of the gear d upon the shaft 0. Upon the outer face of thegear (Z is a cam (Z placed to be moved into contact with the latch 01 ofthe latch-lever. The operation of this part of the machine is asfollows: Upon Upon the gear (Z is brought againstits edge and moves thelever d to disengage or move outward the section (1 of the clutch and toalso release the tension upon the operating-spring d This constructionis quite analogous to that described in my said patent, varying I00therefrom only in a slight detail of construction, which, however, hassome features of value, inIthat it is somewhat simpler in constructionand more direct in its'operation.

The cross-piece a of the frame has integral with it or supports a bed E.This bed has preferably a flat upper surface e, in which is arranged aguideway e, extending from front to back of the machine. In thisguideway is secured a long plate 6 preferably by means of cap-plates eand there is secured to this plate 6 by means of bolts the jacks F F.The extent of forward movement or movement toward the rear of themachine of the plate e is limited by the rear adjustable stop f and thelug or stop f, formed on or attached to the plate. The reverse movementor movement toward the front of the machine is limited by the adjustablestop f and the said lug or stop f, carried by the plate, both sides ofwhich are, it will be seen, utilized as stops in con nection with theadjustable stops f f*. The jacks are made adjustable upon the said plateE by means of the slots f in their base-sections and the attaching-boltsf so that the jacks are movable toward and from each other on the plateand are adjustable in relation to the plate. Each jack preferablycomprises the base f the sleeve f, extending upwardly therefrom, thespindle f guided and held by said sleeve, and the adj usting-nut f onthe lower threaded end of the spindle. Each spindle supports the lasts fIn operation the operator at the front of the machine places a shoe uponthe last of the forward jack, which is then in its advanced or forwardposition, the rear jack being under the nailing devices. He or theassistant then pushes or pulls the jack-plate to move I the forward jackunder the nailing devices. This moves the rear jack to the rear of themachine and in a position to permit the assistant at the rear to place ashoe upon the last of said jack. While this is being done the operatorhas started the machine, attachingthe heel and toplift, if used, to thefirst shoe, and at the completion of the nailing, the second or rearlasthaving a shoe in position, the jack-supporting plate is moved backagain, moving the front jack out of operative position with the nailingdevices and the rear jack into operative position, and the machine isagain started, the operator then removing the heeled shoe andsubstituting an unheeled, while at the completion of the second nailingthe plate is again moved toward the rear of the machine, the secondheeled shoe removed from the rear last, another unheeled substitutedtherefor, and the movement proceeds as before. placed or fed to themachine both from the front of the machine and from the rear insuccessive order, and its capacity is thus very considerably increased.

I prefer in a machine of this organization to use loaded heel-blanks andto feed the loaded heel-blanks and top lifts substantially asdescribedin my said patent.

I have described the construction of the clutch mechanism in detail inthe foregoing specification, indicating the separate parts thereof; butI do not desire in this application to make any claim therefor, and suchdescription is for the purpose of more clearly explaining the operationof the machine.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States= 1. The combination in aheel=nailing machine of heel-nailing devices, a sliding jacksupport andtwo horizontally=adj ustable jacks carried thereby, adapted to beadjusted toward and from each other, and also to be brought alternatelyinto operative position with relation to the nail-driving devices, sub=stantially as described. A

2. In a heel-nailing machine, the combination of a plate or bedextending across the frame of the machine from front to rear, a supportfor the jacks on said plate or bed, means for adjusting the jacks andstops for limiting the movements of the jack-supporting plate in bothdirections, substantially as described.

3. In a-heel-attachin'g. machine, the combination with a reciprocatingcross-head; of a heel-attaching device and a top-lift-attaching devicemounted on said cross-head in diametrical opposition to each other, saidheel and top-lift attaching devices being vertically reversible on saidhead; a jack-support be neath said headadapted to be reciprocated in aright line beneath the heel and top-lift attaching devices; andhorizontally-adjustable jacks or work-supports carried by saidjack-support, said jacks or work-supports being brought into operativerelation to said heel-attaching devices alternately as the j acksupportis reciprocated.
